RAILROAD GRdSS-TIE AND JOINT-CLAMP.

Specification of Letters Patent.

Application filed December 27, 1911. Serial No. 668,029.

To all ivhomt it may b iiccrn:

Be it known that I, DANIEL J. McPnnR- SON, a citizen of the UnitedStates, residing at Cheraw, in the county of Chestorlicld and State ofSouth Carolina, have invented a new and useful Improvement in RailroadGross-Ties and Joint-Clamps, of which the following is a specification.

This invention relates to a railroad tie and joint clamp the. object ofthe invention is to secure the rails upon b .h sides of the track inplace by means of i single bolt to prevent spreading of the rails andalso the ongitudinal creeping of the tie, and a still further object ofthe invention is to' utilize the principle of oppositely operatingwedges for the purpose of forcing a movable portion of the clampingdevices into engagement with the rails thus holding them firmly betweensaid movable portions and fixed clamping members integral with the tie.

In carrying outthe invention I employ the novel features of constructionhereinafter described, pointed out in the claims and shown in theaccompanying. drawings, in which: I

Fi ure 1 is a side elevation'of a tie with the clamping members, railsbeing shown in section. Fig. 2 is a plan view, the ball portions of therails. being partly broken away and the rail webs being shown insection. Fig. 3 is a section on the line 3--3 of Fig.2.

' Fig. 4: is a fragmentary side elevation illus trating the constructionof the clamping plates and operating wedges.

In these drawings 1 represents a metal tie having a flat uppersurfaceupon which rest rails 2. This the has its greater" thickness midway itsends the under surface of the tie sloping upwardlyfrom said centralpoint to points adjacent the ends, which points are beyond the outerfaces of the rails. The

' extreme end portions 3 of the tie are then angled and extenddownwardly and outwardly, these end' poi'tions being the thinnestportions of the tie and practically forming end flanges extendingobliquely with respect to theupper surfaces of the tie; Th sconstruction practically forms a. cavitynpon each side of the center ofthe tie ill.- which packed and effectually prevents any longiinncr endsthe flanges 3 are carried inwardly to overhang the tie and are-then bentup wardly thus forming an angled chair or locking plate 4 beneath whichthe outer base of the rail is adapted tofit and prevents any spreadingofthe rails in the direction of the flanges 3. Slidably mounted upon thetie guide lugs 6 carried by the sides of the tie as shown at 7 to form asecond chair or plate, the plates 7 engaging the inner sides tion. Inorder'to force the plates 5 toward the rails and lock them in osition,each plate has its inner end longitudinally recessed and between theseplates work sub- The sides of the wedge s a d blocks are rounded to fitthe recesses in the ends-.of the plates. along the tie in a straightline without giving to them any vertical movement.

A bolt 9 passes through these blocks trans: versely-to the tie uponwhich work suitable nuts 10, the blocks 8 will be forced togetherthereby forcing theplates 2 apart and into engagement with the rails. a

What I claim is:
